According to the Boruta algorithm analysis, the top 6 important factors were the reasons for seeking medical treatment (Z=126.66), oral health habits (Z=96.44), access to oral health knowledge (Z=66.91), medical needs (Z=62.21), age (Z=57.54), and residence (Z=55.21). ConclusionsLocal ...
The Boruta-Shap algorithm has the following benefits. Robustness - it can produce accurate feature importance rankings even for noisy, high-dimensional datasets. Interpretability is aided by the use of Shapley values, which provide information on how each feature affects model predictions. Boruta-Shap...
1.算法定义算法(Algorithm)是指解题方案的准确而完整的描述,是一系列解决问题的清晰指令,算法代表着用系统的方法描述解决问题的策略机制。也就是说,能够对一定规范的输入,在有限时间内获得所要求的输出。如果一个算法有缺陷,或不适合于某个问题,执行这个算法将不会解决这个问题。不同的算法可能用不同的时间、空间或...

Boruta algorithm is one of the algorithms used to determine the significant variables (feature selection) in a classification model in the machine learning approach, as supervised learning. Our results show that on the German Credit Data from the UCI Machine Learning with 20 variables, feature ...
The Boruta algorithm is a wrapper built around the random forest classification algorithm. It tries to capture all the important, interesting features you might have in your dataset with respect to an outcome variable. First, it duplicates the dataset, and shuffle the values in each column. These...
